CABLE SPLICE. APPLIOATION FILED APR. 17, 1912.

4Be itknown that I, FRED N. Binnen, a resident of Cincinnati, in the county of Hamilton and` yState of Ohio, have invented 5 a -newand useful Improvement in Cable- 'applied .toa spliced cable; F ig 2 is a sec-l ,Splices, of which the following is a full, description, reference beingclear, and exact had to vthe accompanying drawings,vform .inapart of this specication, in whichlFigure 1 is -a sectional view of one form my improved sleeve, showing the device tional vview on the line II-II .of Fig. 1; Fig. 3' is a perspective view ofl one of the glands; and Fig. 4 isa sectional view of a slightly modied form of device.

This .invention relates to cable .splices', Iand more particularly, to closures orseals for the ends of the casings of contiguous sections of an electric cable.

It is designedto and eiiicient device forcoveringthe -Wires at the splice .where theends of the wires of one section of the cable are connected to the ends of the wires ofthe next section, to thereby exclude moisture from,the cable.

A further object of my invention is to provide means for supportingthe-ends of two sections of the cable at two points beyond the stufling boxes, ing movement between injury to the vpacking at the joints between the splice covering and the glands.

am aware that it is old to cover the splice between two contiguous sections of an electric cable by means of a sleeve and to seal thejointsby-means of glands and-a cornpressible packing member. In all of these devices, however, the glands merely engage the casing of the cable for a short distance immediately adjacent to the packing ring, which permits the sections of the cables to oscillate in the glands and thereby injure the packing rings and vdestroy them for-the purpose for which theyare intended.

' The precise nature of my invention will be best companying drawings, which will now be described, .it-being premised, however, that various changes may be made in the details of construction and arrangement of the parts, without departing from the spirit and Specification of Letters Patent. Application tiled April `17, 1,912. Serial No. 691,'531.

.; terior thereof and provide a Cheap, simple4 toxpreventany rock-4v l the ends ofthe cable sections and the sleeve, and thereby avoid understood by reference to the acoHro, AssIeNoR er cnn-HALF 'ro SAM s. EINSTEIN, or GINCINNATI, omo. v k

. scope o f inventionf'as deinedin the appended clalms.

In the drawings, the numerals 2 and 3 sections 4 and of one-'section violual wires of the other section. The .splice 6 iswrapped with the-"usual insulating Patented May 19, 1914t tape and cord 7 to retain the wires in the proper position with relation to each other.

8 designatesea sleeve whichmay be made ofany well known material, vand which is provided with annular flanges 9, on the innear both lends of the sleeve.` This vsleeveis also `provided with v( ).ultwardlyextending annularflanges 10, for the purpose hereinafter-described.

1'1, 11 designate washers which abut against theinternal flanges`9 and which are 4provided with openingsgthrough the centers thereof, vwhich are ,approximately the same diameteras the cute 2 and 3. Each end ofthesleeve 8 is provided-with avgland 12,1 l 1aving outwardly eX- tending annular flanges 13, and are provided with openings, through which the screws 14e extend (the ends of said screws Ahavin-ga screw-threaded engagement with 'screw-threadedopenings in-'the ianges 10.

15 designates packing rings interposed between the washersfll and the glands 12, for forming tight joints between the sleeve 8 and the vcasings 2 and 3. These'gland rings engage the casings at apoint within the sleeve, as indicated at 16, and are also each provided .with extensions having annular openings therethrough for the cables, and whereby the cables remote from the sleeve.

When the device is applied, a gland 12, a packing member 15, a. sleeve or collar 11, and the sleeve 8 are passed on too-ne of the sections of the cable, and the gland, packing member and collar are passed on to the other member. The splice is then made in the4 usual manner, and the sleeve 8 is then r diameter of the casings are supported at a point moved to its proper position with relation to the splice 6. The washers 11, packlng members 15 and glands 12 are then moved into position, and the glands are secured to thesleeve by'means of the screws 14 to compress tliepacking members 15 between the washers 1l and the ends of the glands 12' to expand the packing members against the wall oi' the sleeve and the outer faces of the casings 2 and 3;

In Fig. 4, I have shown an arrangementin which two cables branch from a single cable and in which I have applied the saine reference numerals with the letter. a aliXed. In this construction, the washer 11, packing l5a and gland 12a at onevend of the casing are provided with two openings for the two cable sections which are spliced to the main cable.

The advantages of my invention result from the provision of a sleeve and glands secured thereto, together with expansible packing members interposed between the casings of the cable sections and the sleeve. A further advantage results from the provision of means for supporting the contiguous sections of the splicedcables remote from the inner end of the gland, to thereby provide a long seat or support for the cable section and prevent any rocking movement of the cable sections.

I clailn:

l. A covering fer a cable splice between two sections of a cable, comprising two glands for receiving the ends of the cable sections, a shoulder on each of said glands, a continuous splice-inclosing sleeve eXtending from gland to gland, the smallest inner. diameter of said sleeve being greater than the diameter of the splice to permit the sleeve to be passed over the splice, the shoulders on said glands being arranged to be4 seated washer in' each end of ing the ends of the cable sections,

the sleeve surround there bewithin the ends of the sleeve, a

ing a stuing box formed in each end of the sleeve between the washers and the shoulders on the glands, a packing member in each of said boxes bet-Ween the washers and toward each other to compress said packL ing members to seal the space between/the O'lands, and means for drawing theglands cable sections and the sleeve; substantially as described.

2.*A covering for a cab-le splice between two sections of a cable, comprising two glands, each of said glands having a chant ber therein, openings thro-ugh both ends ot the glands arranged to receive and engage the casings of the cable sections, a shoulder on the inner end' of each of said glands, a

lsleeve extending from gland to gland, the smallest inner diameter of said sl'eeve being greater than the diameter of the splice to permit the sleeve to be passed o-ver the splice, the shoulders on the glands being seated within the casing of the sleeve,A a washer in each end of the sleeve surrounding and engaging the casings of the cable ysections, there bein-g a stu-fling each end of the sleeve and the shoulders on the glands, member in each stuffing box engaging the inner wall of the sleeve and the outer wall of the cable casing, and means for drawing the glands toward the sleeves to compress boxformed in v between the washers i a packing the packing members within the space between the casings of the cable sections and the sleeve; substantially as, described.

In testimony whereof, I have hereunto set my hand.
